A Mountain Goat, they are very rare to see and live above the tree line up on the jagged peaks, and only found in the U.S.A. I lived in Colorado for 12 years and I only had one sighting.
The mountain goat inhabits the Rocky Mountains and Cascade Mountain Range regions of North America, from northern Washington, Idaho and Montana through British Columbia and Alberta, into the southern Yukon and southeastern Alaska. Its northernmost range is said to be along the northern fringe of the Chugach Mountains in southcentral Alaska. Transplanted populations can also be found in such areas as Wyoming, Utah, Nevada, Oregon, Colorado, South Dakota and the Olympic Peninsula of Washington.http://en.wikipedia.org/wiki/Mountain_goat

I used to see them all the time when I lived in Breckenridge. Herds were right off the highway and my dog used to try to get them to play on Quandary Mountain.

Here a vid of a couple of Javelina, I spotted a couple of months ago at the base of South Mountain (Phoenix, AZ). Collard Peccaries (Javelina), are pretty common at South Mountain. They kinda resemble a pig, but don't call 'em a pig. The footage is pretty crappy; I was just learning how to get my camera dialed in.

I took these pics over the last couple weeks. The kits are usually pretty aloof and curious, unless mom's nearby. In that case, they hunker low and make themselves scarce. I haven't heard her signal them from afar, but I believe she does. I know their voices can be somewhat bird-like, so I maybe I heard it but didn't know it.

Canol Road, Northwest Territories. I had about five seconds to find my camera for the shot as this caribou ran by.

The animal had a gaping wound on its neck and a flap of skin about six inches long dangling from it. I figure it as running up the middle of the creek because it has long legs and ran faster in the water than whatever bit it. The only local candidates would have been a grizzly bear or a wolf.
